Covering the whole job description

Seven modules mapped to each section of the posting, plus a reference section and five hands-on labs that make the claims on your resume true.

What the job description is really asking for, and where your resume stands against it.

OSI and TCP-IP, subnetting, DNS, DHCP, port testing with nmap and PowerShell, VLANs and routing.

Windows OS and PowerShell, Server roles, Active Directory, Group Policy, and printing.

The methodology, the eight tickets you will actually be asked about, and hardware diagnosis.

Firewalls, VPN, compliance, EDR and antivirus, and backup strategy.

Hyper-V and VMware, and why a snapshot is not a backup.

Technical questions with answers, STAR stories, resume rewriting, salary and closing.

Port tables, every diagnostic command, and a glossary of every term in the JD.

Five hands-on labs

Built on hardware you already own. Free, and the single highest-value work in this guide.

If you only have an hour

Do subnetting. It is the most tested and most commonly failed topic in the whole process, and it is the cheapest to master.
